Base64 Encoding

You are required to write a Golang program that encodes and decodes a given string using both standard and URL-compatible base64 encoding.

Requirements

The program should import the encoding/base64 package with the b64 name instead of the default base64.
The program should encode the given string using both standard and URL-compatible base64 encoding.
The program should decode the encoded string using both standard and URL-compatible base64 decoding.
The program should print the encoded and decoded strings to the console.

Example

## The string encodes to slightly different values with the
## standard and URL base64 encoders (trailing `+` vs `-`)
## but they both decode to the original string as desired.
$ go run base64-encoding.go
YWJjMTIzIT8kKiYoKSctPUB+
abc123!?$*&()'-=@~

YWJjMTIzIT8kKiYoKSctPUB-
abc123!?$*&()'-=@~

Summary

In this challenge, you learned how to encode and decode a given string using both standard and URL-compatible base64 encoding in Golang.
